Ballot Text

Technical Summary
   Segment Routing (SR) leverages the source routing paradigm.  A node
   steers a packet through a controlled set of instructions, called
   segments, by prepending the packet with an SR header.  In the MPLS
   dataplane, the SR header is instantiated through a label stack. This
   document specifies the forwarding behavior to allow instantiating SR
   over the MPLS dataplane.

Working Group Summary
  There is consensus amongst the Working Group to progress this Document towards becoming a Proposed Standard RFC.

Document Quality
  The Document is quite well written and has undergone editing work to become more focused on its key aspect.
  Several implementations of Segment Routing MPLS exist.
